Watch a triple spiral of 15,000 dominoes fall down

Setting up an intricate domino run isn't easy. It takes a steady hand, hours of work and a lot of patience. Positioning dominoes in the perfect placement to create a spiral, mosaic or pattern -- often referred to as a "domino show" -- is an art form in itself.

The viral video, which was posted on Saturday and already has almost 3 million views, shows step-by-step how this multi-layered triple spiral of dominoes was set up. Of course, after all that painstakingly precise work, the dominoes topple in a magnificent display.

"This is the third largest project I've ever built by myself," Hevesh5 says in the video.
